A mod for Honda EU generator owners

My Honda EU2000I has an electric fuel shut off ( like all others ) when you turn the large knob to the off position. It simply stops the fuel pump from pumping more fuel into the carb because it shuts the motor down. It still leaves the carb full. Sure, you can open the door and manually drain the carb. But what I have done was simply for convenience. Sometimes we think we are going to use the generator in the near future, but don't and we don't take the time to manually drain it. Guess what happens then? A generator that either does not start or runs rough. And why mess with electronics when fuel is the issue. How much more convenient it is to turn the petcock off and walk away and do not even have to turn the large knob to the off position. The gas that remains in the carb does not touch the jets and will not hurt anything. So I guess I do know my Honda generator and being redundant is not the issue.
